` sLIcING-MACH'INE.

Application filed March 23, 1914. Serial No. 826,471.

T o all wpom t may concern.

Be it known'thatl I, HERBERT R. Goon- FELLOW, a subject of tlie King of England', residing at Chicago, in the county of Cook and Statevof Illinois, have invented certain new and useful Improvements in Slicing. Machines, of which the following is a specification.

This invention relates in g-eneral to' slicing machines, but more particularly to the mechanism for holding and for feeding or.

advancing the article to be sliced'.

Heretofore in machines of this character,

I i the article is advanced` to the cutter, through the medium of what lis called the feeding cured or clamped by a clamping bar, that `is adjustably supported by means of two uprights connected with the table.

article is positioned von 'the table Iso that a portion thereof will project in advance ofthe clamping bar and beyond the suptermittently advance the article to the cutporting table; and after the clamping bar is adjusted to secure the article', the table is advanced with respect to the carriage, during the operation ofthe machine, to inter. After the article lilas been=cut until lthe clamping bar Aassumes a position in close proximity to the cutting blade, the 'machine is stopped,` the table retracted and the s clamping bar adjusted to release the article,

tion of the article projecting in advance of f the clamping bar.

to permit the lattery t'o be again .adjustedv lwith respect to the table, and then clamped bythe clamping bar, to again leave a por- This operation is repeated as often as necessary, oruntil the article has been cut up, or the desired quantity cut therefrom. This constantclamping and unclampiig -of the article and the adjustment of the article, 'not only necessitates. .considerable time, but the pressure of the clamping bar upon the article, not only mars or `bruises the article, but Atends to crush or break the saine, under the pressure. To overcome these objections and difficulties',

, andto provide an improved machine of this character having means whereby ,the article,

after being once placed in position, may bef continuously fed to the cutter until the en tire article' has been cut or the desired quan- .tity cut therefrom, without shifting or readjustingthe article' with respect to the The feeding mechanism, is one of the objects of the present invention. `g

A further object is. to provide an' improved machine of this character having means ,whereby the article 'may be suiliciently and properly h eld to be cut', and thehusual clamping bar may be dispensed wit A further object is to provide an im-v proved macliine of this character having accomplishment of other new and useful objects as will appear, the invention consists in the featuresof novelty, in substantially' the construction, combination'and' arrangenient -of the several parts hereinafter more Ifully described andl claimed and shown in the accompanying drawings illustrating ,the invention and in which s Figure@ isa front elevation. of'a slic- Specication of Letters Patent.

Fig. l0 is an enlarged detail view partly in elevation and partly in vertical section of a modified form ef clamping and holdfingA means.

' Referringmore particularly to `the drawings and in the present form of ther invention, the numeral l0 designates generally` a supporting structure, 1.1 designates a ro- Itary cutter which is operatedl from the fly wheel '12. Mounted to1 reciprocate upon tracks or guides 13, 14 supported bythe base of the machine` is a carriage 15, whichl receives its motion from a crank 1 6 connected with a shaft 17, driven Vfrom the ymain, driving shaft of the machine, and

, arranged centrally thereof, so as to extend longitudinally -of the carriage, -and journaledin suitable bearings is a feed'screw 21, whichis preferably arranged below the carriagevand in alinement with a slot 22 which Vextends through the carriage and also longitudinally thereof. This screw 21 is adapted to be intermittently rotated when the carriage is reciprocated, and for that purpose there may be provided an arm 23,

y which is loosely journaled by one extremity,

preferably upon a projecting extremity of the screw 21. The arm 23 is provided with a portion 24, that carriesa pawl 25, the latter being pivoted to the portion 24 so as to 'cooperate with a ratchet wheel 26 that is secured to the screw 21, and an elastic member27 maybe provided which tends normally to hold the pawl in engagement with theratchet wheel 26. Arranged -within the path of movement of the arm 23 by thereciprocation of the carriage 15, is an adjustable abutment 28, and an anti-friction ,roller 29 may be provided on the arm 23 to engage the abutment. .It will thus be seen that when the carriage is reciprocated and moved in one direction, lthe anti-friction roller 29 will engage the abutment 2S and vwill rock the arm, this in turnwill rock the portion 24 of the arm to move the pawl 25 y to rotate the ratchet element 26 and also the `feed screw 21. An elastic member 30 may be provided which tends toturn the arm 23 when the carriage moves 1n a direction to move the arm away from the abutment 28.

Obviously. the'extent of rotation of the screw 21 vwill be controlled by the extent .of movement of the arm 23, and ltlie'ext'ent of movement of the latter will be controlled bythe position of the labutment 28.

Mounted to slideupon the carriage 15 'is an element 31 which is provided with an upright portion 32 the element standing astride of the slot 22 on -the table 15. De-

pending from the'element 31 is a projection4 33, here shown as comprising spaced portions which enter the slot 22 and have laterally projecting portions 34 which extend under vthe carriage top. In order to permit-this element 31 to be removed when desired, the

carriage top may be provided with a removable section 35, which'exteuds alongl a portion of one of the walls of the slot 22 and this section 35 may be removably held in position by means of fastening devices 36, so that when it is desired to remove the element 31, `all that is vnecessary is to remove the fastening devices 36 and lift out the sect-ion after which the portions 33 on the element 31 can be removed from the slot. Obviously any other suitable means may be provided for removably securing the element 31 to the carriage.

Arranged upon theupright portion 32 of the element 31 are a` plurality of articles cngaging prongs 37, here shown in the` form of spirals, which are rotatably supported by the portion 32 t0 project beyond .the face thereof, and connected with each of these PF screws 37 is a gear wheel 3S, and these gear wheels are intermeshed so that when one of A by the rotation of the screw 21, and in order to accomplish this there is provided what is commonly known in this art as a half nut 40 that is connected with a stem 41. The nut 40 projects through the opening 22 to engage the screw 21, and the stem 41 projects through the element V31 and also through a tubular casing 42 and to the extremity of the stem is pivoted a cam de vice 43 which cooperates with theclosed end 44 ofthe housing 42 to raise and lower the half nut with respect to the screw 21. An elastic member 45 in the form of a coil spring is provided which surrounds the stem 41. within the housing 42 and tends normally to move the half nut 40 into engagement witn the screw. Thus it will br manifest that when -the half nut is in engagement with thel screw, and the latter rotated, the. article will be fed forwardly to the cutter 11, and when the cam device 43 is shifted to raise the half nut 40 out o1' engagement with the screw, the element 31 and the article, if the latter is attached thereto, maybe readily moved up on the carriage independently of the screw.

If desired a crank 46 may be connected with the screw 2l for rotating the same. The article holding or clamping means for maintaining the article in position and for holding it securely while being cut by the cutter and during the reciprocation ofthe carriage, embodies spaced uprights 47, 48,

which are arranged adiacent the front of,4

the carriage 15, and in close proximity 'to the cutter 11. These uprights are vadapted tobe moved toward and awayffrom each other ,and the article to be eut is fed oetweenthe uprights, the upright 48 engaging one side of the article, while a clamping element 47,

l@ carried by the other upright47 engages the otherside of the article and coperates with the upright 48 to clamp the article, thereby obviating the necessity ,offthe ordinary and well known clamping bar. These uprights 4l5 47, 48 are preferablysupported by means of a bar 'or guide 49, arranged adjacent the front of the carriage and the uprights are provided respectively with body portions 50,

51, that move beneath the top of the car v riage 15 and through which body portlons the support 49 loosely passes. These bodies 50, 51 are 'preferably of some length to prevent-the uprights from rocking, and the uprights pass through slots 52, 53 provided for 35 that purpose, adjacent the front of the carriage. The support 49 is preferably angular incross section `and the apertures through the bodies 50, 51 through which the support passes, are of the same configuration. The uprights are adapted to be moved toward and away from each other to mov-e the clamping elements 'into and out of elampngfrelation, and in order to obtainlthis movement, the uprights have respectively connected thereto. arms V54, l55 'by means of pin and slot connections 56`, 57 and the arms are respectively supported by means of pivots 58, 59, stopdevices 60, 61 being providedand against which the arms amabut, to limit the movement of the clamping "l extremity to a iiXed support., These elastic members 62, 63 tend normally to move the arms 54,- 55, and consequently theuprights 47, 48 in' a direction toward each other to clamp the article.l In order to separate the clamping elements 47a'and 48, to permit the article to be positioned therebetween, there is provided a lever 64wliich is pivotally supported as at 65 intermediate its ends and projects beyond the side of the carriage 15,

terminating in :an upright portion 66 by means of which the lever 64 may be moved 'about its pivot.

. Pivotally connected with the arm 54 is a link 67,1iaving a slot 68 and a similar link 69 is pivotally connected to the arm 55 and lticle.

is provided with a slot 70. These slots 70 are adapted to Areceive` a pin 71 which is' connected with the lever 64 andwhich'pin travels in 4the slotsvvhen tlieglever is moved. To swing the arms 54, 55about their pivots in a direction to separate the uprights 47,48, and againstthe stress of the elastic members.62, 63, the lever 64' is moved about its pivot 65 so that the pin 71 will be moved in a direction toward the uprights. This .will cause the pin 71 to engagethe endsof' the slots 68, 70 and will through the me-A dium of the links67, 69 rock the arms 54, 55

about the pivots 58, 59 and the uprights will be maintained separated as long as the lever is held in that position. lWhen the article is positioned between the 'clamping elements 47 and 48,-.the lever 64 may beireleased, at

which time' the stress of the elastic members 62, 63 will move the arms 54, 55 in directions to draw the clamping elements toward each other and against the sides'of the 4ar ticle... A stop 72 may be provided Ator limiting the movement of the lever 64 under theJ stress of the elastic members 62, 63.

In ordertomaintain the arms 54, separated,`and lock the lever 64 inrits` adjusted position, a spring catch. 73 may \be provided ihaving ,a cam portion 74 adapted to coperate with the stop 75. y

It will thus be manifest that when the article is secured to the element 31, and the latter is adjusted so that the article will project between the clamping elements 47*l 'and 48, the elastic members 62, 63 will cause the uprights to clamp the sides of th'ear- When in this position the'article, is ready to be sliced. iVhen the machine is set into motion, the carriage 15 will be reciprocated inthe ordinary manner and the article will bel intermittently advanced to the cutter through the medium of the feed 28.` lIn order to hold the article against lateral displacement 'by the engagement therewith of the cutter, it is necessary to provide some abutment against this movement, and therefore there is provided an Iautomatic locking device for locking the lclamping element 47a against retrograde movement. rI'his locking device may be of Vany suitable construction, but a'snnple and eiiicient lock comprises an element 76, (see particularly. Fig. 10)', which is provided' with an opening 77" through 4which the bar or support 49 passes. This element 76is pivotally connected as at 78 with the body 50 of the upright 47 and an elastic member 7 9 is provided between the body Aand the element which tends normally to Yseparate the two. The element 76 is preferably' arranged on oneend of the body and between the pin 56 of the arm 54' andV the adjacent .end ofthe body. This element 76 is so arranged that it will permit the upright 47 screw 21 and the arm 23 and abutment` Thus it will be manifest that when the lirticle is-ipassedbetween the clampingelements, and the carriage 1s advanced so that f the cutter engages the article,'there'will be a tendency ofthe cutter to shift the article laterally on the table, but this shifting movement will be overcome or restricted by the clamping element 47 a, because any tendency to move this elementaway from the clamping element 48 will cause-the element 76 to lock'the clamping element 47a against yretrograde movement.

Vhen' it is-desired to separate the clamping elements so'as to permit another article to be positioned therebetween, this is accomroclrthe arms 54, 55 in the manner already `described and during this rocking movement the pin and slot connection 56, 57 between the arm 54, and the upright 47, carrying 'the,. cla,mpingv element 47a, will-'permit the pin 56 to-move in the slot 57 sufficiently to shift theelement 76 with respect to the body portion of the upright, into such vposition that the opening-77 inthe element 76 will be positioned in alinement With the opening inthe body 50, which will allow the upright 47 to move vfreely in either direction with respect to the bar or 'support 49.

Obviously a locking element 80 similar to the locking element 76" may be provided 'for the clamping element 48, and if desired a roller 8,1a may be providedon the element 48 to reduce the -friction of the element on pendent movements toward and-away from the respective sides of the article.v

The clamping element. 47a is preferably lof a substantially L shape formation, and is 'pivoted intermediate its ends as at 81 to a ycollar 82which is adjustably' mounted on the upright 47, and a spring-83 is provided `for holding the'clamping element in the4 positionv shown in Figs. 1 and lOwhen not in use.' This positions the clamping element to receive the side of the article vand to cooperate with the element 48 to clamp the article. y The collar which supports the element 47a is adjustably held o n the upright by means ot a fasteningdevice 85. The upright is preferably angular in cross section to. maintain the clamping element 47a in proper position.

While the preferred form of theinvention has been herein shown and described, it is to be understood that many changes may be made in the details of construction and in the combination and arrangement of the several parts, without departing from the spirit of this invention.
